It was definitely user error! Once the counter passed 16 and went back to 1 I stopped it. Didn’t realize I had to let it keep going until “END”. It appears the first part backs up the patterns then the second part is the samples which takes longer.

Tried both in Audacity and Ableton multiple times now, I nearly always get an error, only when the gain on my audio interface was at MAX did I at least get a reaction from the PO-33 but that also failed after some % The idea is so good, but never knowing if your backup works (if I finally get ONE to work) is sad.

I’m sorry to post so much, I’ll try to limit it, but I have over 12 tries now. Even ordered cables that are small chinch to big chinch so I knew it was not my adapter. I recorded in Ableton, Audacity, through my Mic in and through a Steinberg U242 but NOTHING works. I tried some files that are flying around online but they also got an error after 1 second or weren’t even recognized. Could someone upload me one of his working backups so I could try? Maybe my unit is damaged.
